Cute!
My favorite part is I can totally imagine them behaving that way.
You got some of there characteristics spot on.
Naruto would have done that for a crush(the dinner set up, wiping away her makeup and saying "always next year)".
Luna could have behaved that way(checking if shes awake, letting her friends handle make up, and her answers to Naruto's cute gestures, like kiss his nose)
I'm assuming their both about 14-16 years old. All around nice one-shot :-)
